16 Claims.

This invention relates to shoe supports, and more particularly to supports of that type in which there is a toe rest for supporting a last and shoe at the top of the forepart and a heel pin for engaging the heel end of the last in its spindle hole. The invention is herein illustrated as embodied in a shoe support serving as part of a machine for lasting the toe ends of felt shoes, but it is to be understood that it is not thus limited in its applicability.

In shoe supports of the above-mentioned type the heel pin has sometimes been mounted to tip in a direction to press the forepart of the shoe on the toe rest and in the opposite direction, a spring also being sometimes provided for tipping the pin in the direction to press the shoe on the toe rest to assist in holding the shoe firmly on the support. An object of the present invention is to provide improved means for con trolling a heel pin thus mounted for tipping movements, and in one aspect to provide controlling means so constructed as to permit and facilitate adjusting movements of the heel pin toward and from the toe rest to accommodate lasts and shoes of diiferent sizes. For the purpose in view the construction herein shown comprises a device that is movable to tip the heel pin in any position to which it is adjusted and relatively to which the pin is movable in its adjustment, the device being arranged for different portions thereof to act on the pin in different adjusted positions of the pin. More particularly, as illustrated, the controlling device has a slot extending along the path of adjusting movement of the heel pin, and connected to the pin for tipping it is a member which is movable along the slot to maintain it in operative relation to the controlling device in all positions of the pin. As further herein shown, the controlling device is movable by a treadle to tip the pin into position to receive a last and shoe and is movable by a spring to press the shoe on the toe rest. In accordance with another feature of the invention a toggle is provided through which to tip the heel pin, the toggle in the construction shown being arranged to be operated by the above-mentioned controlling device in any position of adjustment of the pin.

The above and other features of the inventicn. including various novel details of construction and combinations of parts, will now be more particularly described by reference to the accompanying drawings and pointed out in the claims.

In the drawings,

Fig. 1 is a view in front elevation of a shoe support constructed in accordance with the present invention and applied to a felt shoe toe-lasting machine;

Fig. 2 is a view in front elevation on an enlarged scale, with parts broken away, showing a portion of the novel shoe support in its relation to a shoe; and

Fig. 3 is a view in plan of a portion of the support.

Mounted on the frame 10 of the machine shown in Fig. 1 is toe-lasting mechanism which, in combination with the shoe-supporting means hereinafter described, is especially intended for use in lasting the toes of felt shoes presented to the machine in the condition illustrated in Fig. 2, although it is to be understood that a machine such as shown is by no means limited to that particular use. This toe-lasting mechanism need not be described in detail, since it is shown merely to illustrate one use of the novel shoe support and is, moreover, of well-known construction common heretofore in bed-lasting machines, the characteristic features of which have been disclosed in various prior United States Letters Patent, including Letters Patent No. 1,018,477, granted on February 7, 1912, upon an application of Matthias Brock.- It will be understood that the mechanism includes toe-embracing wipers 12 that are advanced and closed to wipe the toe end portion of an upper inwardly over the bottom of a last by means of a hand lever 14.

For supporting the last and shoe in position for the toe-lasting operation there is provided a toe rest 16 arranged to engage the shoe at the top of the forepart, the arrangement of this and other parts, in the machine herein shown, being such that the shoe is supported bottom upward in a substantially horizontal position. The toe rest 16 is mounted on a stem 18 connected to the toe-lasting mechanism in substantially the same manner as in prior bed-lasting machines of the well-known type above referred to, the stem, however, in the machine herein shown, being supported on a plate 20 which is fast on a bracket 22 secured to the frame. On the upper face of this bracket is fastened a plate 24 the opposite side portions of which are arranged to project beyond the sides of the bracket and have upper faces 26 (Fig. 3) arranged to serve as guideways for a heel pin support or carrier 28 provided with flanges that extend under the side portions of the plate 24 to hold the carrier on the guideways 26, as illustrated in Fig.2. Supported on the carrier 28 in a manner more particularly hereinafter described is a block 30 arranged for supporting engagement with the top face of the heel end of the last, and projecting upwardly from this block is a heel pin 32 arranged to engage the heel end of the last in the usual spindle hole. The carrier 28 is movable along the guideways 26' to adjust the block 30 and the heel pin 32 toward or from the toe rest 16 for properly supporting lasts and shoes of different sizes. Since lasts of different sizes differ in height at their heel ends, the guideways 26 are inclined somewhat upwardly toward the toe rest, so that the bottom faces of the heel ends of the different lasts are supported at substantially the same height. For maintaining the carrier 28 in any adjusted position there is provided a pawl 34 arranged to cooperate with ratchet teeth 36 formed on the plate 24, the pawl being fast on a rock shaft 3'7 on the carrier 28. A spring 38 seated in the carrier 28 holds the pawl in engagement'with'the'ratchet teeth. To adjust the car rier28' toward'the toe rest all that the operator needs to do is to push it along the guideways 26, the pawl'automatically looking it against reverse movement. Before adjusting the carrier in the opposite direction it is-necessary to lift the pawl from the ratchet teeth, and for this purpose there isprovided an arm 40 fast on the rock shait 37.

The block 30 and itsheel pin 22 are pivoted at 42' on the carrier 28-for tipping movements in opposite directions lengthwise of the last and shoe. By tipping movement toward the toe rest the heel pin may accordingly be utilized, through its tendency also to tip the last, to press the forepart of the-shoe down on the toe rest and thus to hold the shoe firmly in position for the toelasting operation.- As means through which to control the heel pin and to tip it in the opposite directions there isprovided a toggle comprising a pairof links 44 and" 46 pivotally connected together by a-pin 48 a reduced portion of which extends through the two links and is held in place'by a nut 50 as shown in Fig; 3. The link 44 is pivotally mounted on a pin 52which is fast in 3 lug 54" projecting from the block 30, and the link 46is pivotally mounted on a pin 56 fast in the carrier 28i Mounted'on an enlarged por tion of the'pin-ifl, at the knee joint of'the toggle, is a roll 58. For controlling and operating the toggle; and accordingly tipping the heel pin 32, there is provided a controlling device or'member 60 which is fasten the upper end of a rod 62 vertically movable in bearings on the frame of the machine, the upper portion of the member 60 extending along the path of adjusting movement of the carrier 28 and the heel pin and being provided with a slot 64 in which the'roll' 58 lies. The slot 64 is inclined in parallel relation to the inclined guideways 26 for the carrier 28, 'and accordingly provides on the member 60 upper and lower surfacesextending'in parallel relation to the path of adjustingmovement of the heel pin andarranged-to engage the roll 58. It will thus be seen that the member 60 is stationary during adjustments of the heel pin toward or from the toe rest and that by such adjustments the roll 58 is carried-along the slot 64 to different positions so as to be engaged by different portions of the member 60'or of the surfaces at the upper and lower sides of the slot. The member 60 for tipping the heel pin accordingly maintains an operative relation to the pin in all positions of adjustment of the latter while, permitting the pin tobereadily'adjusted when desired.

In the construction shown the member 60 is moved in a downward direction by a spring 66 connected to the lower end of the rod 62 and to the frame of the machine, and it is moved in an upward direction by a treadle 68 pivoted at '70 on the frame and connected by a link 72 to the rod 62. When there is no shoe in the machine downward movement of the member 60 is limited by its engagement with a bearing member '74 through which the rod 62 slides, as shown in Fig. 1. When it is desired to mount a last and shoe on the heel pin 32 the operator depresses the treadle 68, thereby raising the member 60 whichacts through the toggle 44, 46 to tip the heel pin in a direction away from the toe rest 16 so that a last may be readily mounted on the pin. The operator thereafter releases the treadle, whereupon the spring 66 acts to tip the heel pin toward the toe rest, thereby causing the pin by its action on the last to press the forepart of the shoe down on the toe rest. When it is desired to remove the last and shoe the operator again depresses the treadle. It will be evident that the member 60 controlled as described acts in the same manner'on the heel pin in all positions of adjustment of the pin and its carrier 28 toward or from'the toe rest.
